PIPE-JOINT FOR GAS-MAINS.

SPECIFICATION forming part of Letters Patent No. 340,267, dated April 20, 1886.

Application filed March 1,1886.

To all whom it may concern/.-

Be it known that I, GEORGE WESTINGHOUSE, Jr., residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered a certain new'and useful Improvement in Pipe-Joints for Gas-Mains, of which improvement the following is a specification.

In theaccompanying drawings, which make part of this specification, Figures 1 to 4 are longitudinalhalf-sections through pipe-joints, illustrating the application of my invention.

My invention relates to pipe-joints of the bowl and spigot type; and its object is to attain substantially the advantages of a turned joint without the expense of machine work upon the pi pe-sections.

To this end my invention, generally stated, consists in the combination of a pipe-section having a bowl or socket end, a pipe-section having a plain or spigot end inserted in said bowl, a strip or plate of sheet metal inter posed in annular form "between the bowl and spigot, and a packing of soft metal filling the space within the bowl on each side of said strip.-

The improvement claimed is hereinafter fully set forth.

In the practice of my invention the spigot end of a pi pe-section, 1, is inserted in the usual manner in the bowl 2 of the adjacent pipesection 1. A strip or plate of sheet metal, the width of which should be equal to or some what greater than the depth of the bowl, is bent into a ring of such diameter as to fit in the bowl about midway between its inner surface and the outer surface of the spigot, and is inserted in such position in the bowl. The strip 3 may be of either a single or a double thickness of metal, as preferred, the latter construction being shown in the drawings, and when in two thicknesses these may be 0ppositely grooved or corrugated, as shown in Figs. 2 and 4, to form a chamber, 7, for intercepting leakage from the main. A packing,

4, of lead or other softmetal, is run into the spaces within the bowl on both sides of the strip, and is calked in the usualmanner at the outer end of the bowl. The two sections Serial No. 193,559. (No model.)

of the packing being thus separated 16% the smooth surfaces of the strip 3, the advantage of a turned joint is practically obtained under movement of either of the connected sections without the material expense involved in forming such ajoint by machine-work.

Figs. 3 and 4 illustrate applications of my improvement in which a packing, 5, of vulcanite, compressed fiber, paper, or other suitable material is inserted between the two thicknesses of the dividing-strip 3, the spaces on the opposite sides of said thicknesses being filled with soft-metal packing, asin the former case.

I claim herein as my invention- 1. The combination of a bowl or socket ended pipe-section, a plain or spigot ended pipe-section inserted therein, an annular strip or plate of sheet metal interposed between the bowl and spigot, and a packing of soft metal filling the space within the bowl on each side of said strip, substantially as set forth.

2. The combination of a bowl or socket ended pipe-section, a plain or spigot ended section inserted therein, two adjacent annular strips or plates of sheet metal grooved or corrngatcd in opposite directions to form a leakage-chamber and interposed between the bowl and spigot, and a packing of soft metal filling the spaces between said strips and the surfaces of the bowl and spigot, substantially as set forth. Y

3. The combination of a bowl or socket ended pipe-section, a plain or spigot ended pipe-section inserted therein, two adjacent annular strips or plates of metal interposed between the bowl and spigot, a packing of compressed'fiber or like material fitting between said plates, and a packing of soft metal filling the spaces between said strips and the surfaces of the bowl and spigot, substantially as set forth.

In testimony whereof I have my hand.

PIPE-JOINT FOR GAS-MAINS.

SPECIFICATION forming part of Letters Patent No. 340,267, dated April 2 0, 1886.

Application filed March 1,1886. Serial No. 193,559. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE WESTINGHOUSE, J r., residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered a certain new and useful Improvement in Pipe-Joints for Gas'Mains, of which improvement the following is a specification.

In theaccompanying drawings. which make part of this specification, Figures 1 to 4 are longitudinal half-sections through pipe-joints, illustrating the application of my invention.

My invention relates to pipe-joints of the bowl and spigot type; and its object is to attain substantially the advantages of a turned joint without the expense of machine work upon the pipe-sections.

To this end my invention, generally stated, consists in the combination of a pipe-section having a bowl or socket end, a pipe-section having a plain or spigot end inserted in said bowl, a strip or plate of sheet metal interposed in annular form between the bowl and spigot, and a packing of soft metal filling the space within the bowl on each side of said strip.

The improvement claimed is hereinafter fully set forth.

In the practice of my invention the spigot end of a pipe-section, 1, is inserted in the usual manner in the bowl 2 of the adjacent pipesection 1. A strip or plate of sheet metal, the width of which should be equal to or somewhat greater than the depth of the bowl, is bent into a ring of such diameter as to fit in the bowl about midway between its inne'rsurface and the outer surface of the spigot, and is inserted in such position in the bowl. The strip 3 may be of either a single or a double thickness of metal, as preferred, the latter construction being shown in the drawings, and when in two thicknesses these may be oppositely grooved or corrugated as shown in Figs. 2 and at, to form a chamber, 7, for intercepting leakage from the main. A packing,

4., of lead or other soft metal, is run into the spaces within the bowl on both sides of the strip, and is calked in the usualmanner at the outer end of the bowl. The two sections of the packing being thus separated 5% the smooth surfaces of the strip 3, the advantage of a turned joint is practically obtained under movement of either of the connected sections without the material expense involved in forming such ajoint by machine-work,

Figs. 3 and 4 illustrate applications of my improvement in which a packing, 5, of vulcanite, compressed fiber, paper, or other suitable material is inserted between the two thicknesses of the dividing-strip 3, the spaces on the opposite sides of said thicknesses being filled with soft-metal packing, as in the former case.

I claim herein as my invention- 1. The combination of a bowl or socket ended pipe-section, a plain or spigot ended pipe-section inserted therein, an annular strip or plate of sheet metal interposed between the bowl and spigot, and a packing of soft metal filling the space within the bowl on each side of said strip, substantially as set forth.

2. The combination of a bowl or socket ended pipe-section, a plain or spigot ended section inserted therein, two adjacent annular strips or plates of sheet metal grooved or corrugated in opposite directions to form a leakage-chamber and interposed between the bowl and spigot, and a packing of soft metal filling the spaces between said strips and the surfaces of the bowl and spigot, substantially as set forth.

3. The combination of a bowl or socket ended pipesection, a plain or spigot ended pipe-section inserted therein, two adjacent annular strips or plates of metal interposed between the bowl and spigot, a packing of compressed'fiber or like material fitting between said plates, and a packing of soft metal filling the spaces between said strips and the surfaces of the bowl and spigot, substantially as set forth.

In testimony whereof I have my hand.
